The treatment must be tailored and adapted to your needs. Talk to your healthcare practitioner about your symptoms. There is help to get.

Transanal irrigation (TAI)

Transanal irrigation (TAI) is a method of e­ffectively emptying a larger part of the bowel, by introducing lukewarm water into the rectum. The water can stimulate the peristaltic movements of the bowels which helps to effectively empty the bowel. With Navina Systems there is always a choice to find a solution that fits your needs following rectal surgery. The therapy has been shown to be effective in 8 out of 10 patients with major LARS (Cura Pales, et al., 2019; Enriquez-Navascues et al., 2019)

No more bowel accidents

Starting with TAI is no quick fix and will require commitment and patience from you. When the training period is over and your bowel has adapted to the method, the aim is often to irrigate every other day and be continent in-between. The purpose of TAI is to restore a regular and well-functioning bowel, allowing you to lead a more normal life and get in control. Talk to your health care provider about Navina Systems.
